Update Marked

[k-utsumi]

Update Marked package as markdown does not work as expected.

e.g.

<details>

```
foo
```
</details>

I referred to Marked code.

Thanks for this! It looks OK, I'm just curious as to the reason why we have to "fix" the code renderer? I'm not saying we don't have to, it would just be good to understand why before this gets merged.

@k-utsumi Could you answer the above if you get a chance? I'm apprehensive to merge without knowing why we're making this change.

I'm sorry to reply late.
If you can wait, I want to update Marked once again with resolving Issue like markedjs/marked#1374

The reason for updating Marked is to facilitate the transfer of the document writing tool.
I think fractals are very useful, but others may not think so.
So I think ease of transfer is important.
